netstat cuts off ip addresses
 

I have connections shown as ipv6 (I think, They have ::ffff: appended to them) from addresses which are not ipv6 (it shows them as ipv6 when they are not?). They get cut off so I some times have an address like:

::ffff:192.168.1.:5030

in my active connections.

Why does this happen and how can I fix it?

Try redirecting the stream to an output file and see if everything shows up there.

For IPv6 addresses, it's legal to represent consecutive zeros as :: . Google for the rules of IPv6 address notation, you should find an explanation.

Yes. But these aren't supposed to be ipv6 addresses. I don't even have a router setup for ipv6.

netstat options
 

Netstat is cutting off part of the address , try the --wide option:

Example.
netstat --wide -an
